invention provides an improvedv gate spring and mounting and, generally-stated,

consistsvof the lnovel devices, combinations of devices.V and arrangement of parts hereinafter described an'ddened in theclaims.

They -preferredformof the invention isillustrated inthe laccompanying drawings, wherein like characters indicatelike parts throughout'thefseveral views. Y Referring `to the drawings: y

Fig. lis an elevationshowing a gate em; bodyingV and installed my invention; and Y Y Y Fig. 2 is a fragmentary view with some parts invertical section, .illustrating in detail the manner of mounting the gate. f

f The gate itself may take different forms, but, as shown, it comprises an approximately rectangular marginal frame 3 madeup of Vpipe sections 3, 4, 5, 6 and 7. In this particular structure illustrated, the pipe sections 4 and 5 are connected to theV down? turned side Vmembers of the U-shaped lpipe Y section 3 by T-couplings18 that also serve to lconnect the sides of the gate frame to the ends of the cross pipemember 7, and

. the ends of the lower pipe sections arel connected to the lower'ends of the pipe sectionsfl and 5 by elbow couplings 9., The

' body of the frame is/shown as iilled in by a woven wir-e 10. This gate, as shown, Vis mountedbetween u right fence posts 11 and 12, said posts, as il ustrated, being pipe sections Aproperly supported by having their ends set into the ground or otherwise rigid` ly held., The gate is supported for lateral swinging movements lfrom the -post'll'by means yof an upper gate-supporting bracket 13 and a lowery gate-supporting bracketV 14. The projecting end of the upperbracket 13 is` tubular andthe 'downturned adjacetnt portionof the frame member 10 is passed therethrough and pivotally mounted therein. vThe lower bracket llaiat its extended end, is in the form of a sleeve 15 into which is set a pivot hub 16 that is capable of ro-` tary adjustments in said sleeve but is rigidly held therein'by'a set screw17 Thisivot hub 16 has ,an upwardlyextended re ucedv trunnion 18 f anda similar and axially aligned depending trunnion` 19. The tubu lar framepmember 5 issectioned or, in other p words,'has a piece `cutout so that its severedl in accordance with applyingl the spring and 'Y ends are telescoped and 19. p 1 Y Y The gate thus mounted `is free to swing onto the trunnions 18 in the sleeve-like upperporticn' 13- and on .theitruiinions 18and 1-9. .To" facilitate ro# jtary adjustments'of the hub 16, it is shown as formed with an exposed angular or nutp 'lhel gate spring is inthe .form of a flat spring-tempered leaf or bar 21, thelower trunnion-18,and theupper end ofv which'V is set into a slit formed 'in a plug22 rigidly secured in the hinged arm yof the frame inember 3 by a rivet orbolt 23. By this vara Vrangement,.the lower end ofthe spring Ais anchored against rotary` movement, while the upper end of thev spring isconnected for rotary or oscillatory movements with theV gate. Obviously, the said spring 21 willV tend to assume a `flat and tion.

Ifthe .gate be adouble-swinging gate,

and then released, the spring will restorethat is, one arranged vto swing v1n either direction from a closed j position,V then the hub 16, which affords a like ange20, to which a wrench maybe applied 'Y c5 end ofwhich is set into `a slit' formed "inthe Y' straight condi- The spring 21, as is evident, isa torj* Y vsion spring, that is, it acts under vtorque strain-to close thel gate.

`and with such adjustment, it is evident that f 'when the gate is swung Vin either directionl the Vgate to its closed position; but' ify the gate be oneV arranged to swing to a closed f position against a stop, then the, hub lmay be adjusted so as to normally liold the gate closed under any desired tension.` Obvious-y 1y, by loosening the set screwv 17 and applying a wrench to the 'iangeA 20, the hub 16 may be quickly'.V adjusted toVv any desired position'V and then 'secured bytightening the j set-screw.

To afford a' closed chamber fory the spring, a plug'24; is `shown as placed in the pipe sect-ion 7,' as 'shown in Fig. 2. By

referenceto Fig. 2, it will be noted that the 'A tubular member pivotitlly extended throw;4
